Many people believe that during a cesarean delivery, the fetus is not stretched and dilated, so there is no damage or laxity to the vaginal tissues. In fact, this is not the case. Pregnancy and delivery are two separate factors that affect the functional status of the pelvic floor muscles. During pregnancy, as the fetus grows and the amniotic fluid increases, the uterus slowly enlarges and the pressure on the pelvic floor muscles increases day by day. Moreover, due to the unique posture of the pregnant woman, the abdomen protrudes, the lumbar spine curvature increases and the center of gravity of the enlarged uterus acts almost completely on the pelvic floor muscles, so the pelvic floor is under very high pressure during pregnancy. In addition, the hormonal changes during pregnancy, especially the increased secretion of relaxin, cause the ligaments and fascia in the vagina and pelvic floor to become increasingly lax. Thus, the pregnancy alone has a variety of adverse effects on the vaginal and pelvic floor tissues. Although the fetus is not delivered vaginally by cesarean section, it is not wise to try to avoid the effects on the pelvic floor and vagina by having a cesarean section. After cesarean delivery, the recovery of the vagina should also be noted at the 42-day postpartum examination.
